Error while using runtime: option is not avaiable #324

Closed matthisholleville closed 6 months ago

matthisholleville commented 6 months ago

Hello,

I'm currently using the HAProxy Helm chart, and I'm encountering an error when trying to use the /runtime APIs.

Whenever I attempt to query any of the runtime endpoints from my pod, I encounter an error of this type:

{
    "code": 500,
    "message": "runtime: option is not available"
}

I notice that there's already an open issue #289 with a seemingly similar problem.

Here are the details of the versions and configuration:

The issue was between the chair and the keyboard (as often happens, haha). For those interested, I was missing the socket declaration in the HAProxy configuration.

global
      stats socket /var/run/api.sock user haproxy group haproxy mode 660 level admin expose-fd listeners

....

It would be great if the error message could be more explicit! 😄
